Geometry Chapter 10

A tangent line must be perpendicular to a radius

• True

• False

A line that intersects a circle in exactly 1 point

• chord

• tangent

• secant

• diameter

A segment whose endpoints are on the circle

• chord

• diameter

• radius

• secant

If a tangent and a chord intersect, then each angle formed is 1/2 of its intercepted arc

• True

• False

If 2 chords intersect inside the circle, then each angle is 1/2 the sum of the intercepted arc and its vertical arc

• True

• False

2 chords intersect in a circle:

• tangent2=external x whole

• external x whole=external x whole

• part x part=part x part

2 secant segments are drawn to a circle:

• part x part=part x part

• external x whole=external x whole

• tangent2=external x whole

L/pi X diameter = angle measure /360

• arc length

• chord length

• tangent length

• secant length

Given circle P, identify a radius

• segment PC

• segment EH

• segment CG

• line ML

Given circle P, identify a tangent.

• Line LM

• Line EN

• Segment JB

• none of these
